Changes

3.0.0 / 2013-01-19

  • Change fold such that errors that reach it are thrown.
  • remove dependency on eventual & watchables

2.0.0 / 2012-11-23

  • Factor out [reducible][https://github.com/Gozala/reducible] abstraction into own package, that way we can avoid most of the API breaks.
  • Remove most of the non-essential / not commonly used APIs.
  • Remove reduce function in favor of fold with a more useful API.

1.0.3 / 2012-11-10

  • Update dependencies

1.0.2 / 2012-11-09

  • Improve definition for arguments object.

1.0.1 / 2012-11-06

  • Define API for lazy creation of reducibles.
  • Improvements for print function so that it could handle objects with circular references.
  • Fix reduce so that errors thrown by handler are captured and cause rejections in returned promise.

1.0.0 / 2012-11-02

  • Add integration for browser based testing using phantomify.
  • Removed lots of low level APIs like transform, trasformer, convert in favor of enhanced reducible that also takes care of collection normalizations.
  • Errors no longer require boxing, instances of Error-s are treated as exceptions in a collection. Such collections are considered as broken & after error no values will be dispatched. Also emit-ing errors on signal / channel marks them as broken.
  • End of stream no longer requires boxing, it's just a special data value that indicates end of stream. Anything followed in a collection passed that is ignored, also reducible's will ignore any subsequent values and will return reduced result to signal they've done consuming.
  • Adding missing test cases.
  • Improvement to a print function that now also works in the browser.
  • New low level utility function reducer that is just a sugar over reducible that takes care of the boilerplate code for stateless transformation functions.
  • New normalize utility function that can be used to wrap collections that are not guaranteed to comply to API contracts. Resulting collection is guaranteed to end or error only once and always pass in accumulated value returned in a last iteration.

0.2.1 / 2012-10-30

  • Fix bug in hub implementation that was not multiplexing on values that have derived from it like channel for example.

0.2.0 / 2012-10-28

  • Break API change for signal / channel. They no longer throw exceptions on attempts to close or emit more data instead they return accumulated boxed value to signal they're closed.
  • Implement pipe that can be used to pipe input right to an output (signal / channel / whatever implements emit).

0.1.6 / 2012-10-26

  • Add a lot more tests.
  • Create index with all end user functions.
  • Fix subtle bug in hub implementation.
  • Fix bug in delay implementation.

0.1.5 / 2012-10-25

  • Fix bug in implementation of capture that caused multiple ends.
  • Implement delay utility module.
  • Fix flatten that in edge cases leaked end of stream before it actually ended.
  • Implement lot's of new tests.

0.1.4 / 2012-10-24

  • Add transformation support for primitive types.

0.1.3 / 2012-10-24

  • Removed JSHint comments.
  • Remove experimental modules.
  • Implement zip function.
  • Remove dependency on zip package.

0.1.2 / 2012-10-24

  • Make reduce API on eventuals equivalent of API on values they resolve to.

0.1.1 / 2012-10-23

  • Define implementation of accumulate for eventual data types.

0.1.0 / 2012-10-21

  • Refactor reducers into idiomatic node structure of function per module.
  • Document each individual function.

0.0.3 / 2012-10-15

  • Implement client http API for reducers.
  • Implement clojure like reductions function.
  • Implement experimental adjust function.
  • Implement concat for parallel data structures.
  • Update to eventuals@0.3.0

0.0.2 / 2012-07-23

  • Rename channel abstraction to signal and define alternative channel abstraction
  • Implement lazy stream abstraction.
  • Extend accumulate with a default implementation for all values.
  • Define experimental Binoid type.
  • Define sequential decorator.
  • Implement error handling for reducers.
  • Implement capture function for error handling.
  • Implement hub function for sharing sequences across multiple consumers.
  • Make core independent of promise abstraction.
  • Implement list type.

0.0.1 / 2012-05-19

  • Initial release
